The critical temperature and critical pressure of a gas are 31ºC and 728 atmospheres respectively. Calculate the constants 'a' and 'b'.
Text Solution
Verified by ExpertsThe correct answer is:
A
(a = 0.36 atm litre 2 mole –2 , b = 4.28 × 10 –3 litre/mole)
T C = 273 + 31 = 304 K, P C = 728 atm
T C = 
and ( P C = 
∴ 
= 
× 
= 
On substitution 
= 
∴ b = 
= 4.28 × 10 –3 litre/mole
Now, vc T C = 
∴ a = 
= 
= 0.36 atm litre 2 mole –2 Ans.
